SLES8 + Dom 6.5.1 --> question to occured crash caused by memory....

Dear all,

unfortunately I experienced my first crash of our productiv Domino-Server
(Server rans very fine with normal workload for weeks, at the moment of
crashing the workload reached a peak but not more than 280 users...)

- HP Proliant ML 570 - dual 2,8 Ghz Proc (Hyperthreadind deactivated)
4 GB RAM
- SLES 8 with SP3
- Domino 6.5.1 eng. with Suse ExtensionPack

Please find below the serverconsole at moment of crash.... and a workaround
from IBM Side...
Anybody experienced the same and tried out this IBM Notes.ini settings for
Memory ?

By the way: I am using the Domino Extension Pack from SUSE and "more than
1000" users is NOT activated in domino-script, because we only have maximum
600 Users here.....
Should i activate this basically regardless how many users i have on
machine ??

Any help/hint/tipp is really highly appreciated... !!

Thanks and best regards,
Alex Hofer
